<h2>
Purpose
</h2>
Evaluate derivatives of GLM outputs with respect to weights.

<p><h2>
Synopsis
</h2>
<PRE>

g = glmderiv(net, x)
</PRE>


<p><h2>
Description
</h2>
<CODE>g = glmderiv(net, x)</CODE> takes a network data structure <CODE>net</CODE> and a matrix
of input vectors <CODE>x</CODE> and returns a three-index matrix mat{g} whose 
<CODE>i</CODE>, <CODE>j</CODE>, <CODE>k</CODE>
element contains the derivative of network output <CODE>k</CODE> with respect to
weight or bias parameter <CODE>j</CODE> for input pattern <CODE>i</CODE>. The ordering of the
weight and bias parameters is defined by <CODE>glmunpak</CODE>.
